Jul 25, 2014 I have to mill a 3/16 wide slot in 8620. It is 2 long, thickness starts at .1 and ends at .5.....Width can be +.020 -0 I have some 3/16 dia 3 flute solid carbide end mills, 60* HLX TNC 5/8 LOC Is there something that will work better? I have 60 slots to do. Recommended speed and feed?
The Importance of Milling Speed and Feed Calculations. The spindle speed is derived from cutting feeds and speeds, it is one of the ideal cutting conditions for a tool, if the condition is not ideal, the adjustment of spindle speed is necessary, usually reduce in RPM or modify it to a correct value.

Useful Formulas for End Milling. Cutting Speed Vc = .262 x D1 x rpm Revolutions / Min. rpm=3.82 x Vc / D1 Feed Rate fm = ft x n x rpm Feed Rate / Tooth ft = fm / (n x rpm) Symbols Used: D1 = End Mill Diameter rpm = Revolutions per Minute Vc = Cutting Speed, feet per Minute ft = Feed, Inches / Tooth fm = Feed, Inches / Revolution n = number of teeth

Sep 24, 2012 It varies depending what tool you use. When I'm surfacing with say my 3/4 ballnose insert, I punch numbers in here Sandvik Coromant Online Product Catalogue in cutting data and I get the numbers I need for effective chip. So for example if I'm cutting 44w plate Mild Steel and I have .03 of material on the surface, I will run 1375 SFM with a .042/rev feed.
